One of the more unique features of the MK&P layout was not seen by the casual visitor. The materials and many of the techniques used for construction were not ones traditionally used in building a model railroad layout. Plywood so commonly used in constructing everything from the conventional 4x8 layout to the club-sized pike was nowhere to be found. We chose instead to use steel studs and extruded foam insulation as our basic building materials. We are not the first to employ these common home building materials for a layout, but the choice still is an unusual one. Because the use of foam and steel are relatively new, how to build with these materials is still not fully explored. Much of what we did we made up as we went. I have collected several photos of my own along with many from other sources. In the early days of construction I did not have a suitable camera of my own. So most of these early photos were taken by Glenn Koproske.
